Why you shouldn't order pizza online

Ordering food online is probably the best idea since the Internet — but sadly, it has a major downside, according to one study.

Researchers from three big universities confirmed that ordering online — specifically pizza — means more calories and more money out of the bank. The study involved one pizza chain and more than 160,000 orders from 56,000 households between 2007 and 2011. It compared orders made online and over the phone from the same households and found that the most over-the-top or special orders came in via the Internet.

Why? We simply let our guard down. One Duke economics professor involved in the study says quote -- "When we think we're free from social judgments, we'll order what we really want." Basically, calling a real person means we have to tell them that we really want all those toppings on our pizza - or pizzas - and we might get a little self conscious about it. Not that the employee taking our order should care anyway. Just remember, more ingredients means more money.
